Has the educational process failed here?
Come on man.. no need to speak all ghetto.

As long as your koni's are the race valved they should be able handle those rates easilly.
Heck I have heard of people using the regular OTS konis with a 500lb springs before too.
I dont know how long they last but its been done.
If thats what you can afford then get them.
You also should check our for sale thread you might be able to pick up a set of eibachs cheap too.

If you actually searched the forum, you'd find what your looking for.
But since you took less time to type, (speed typing), and even less time to search you got a smart *** response.

What you perpose will work.
Next time search.

For your purposes, that brand will be fine. Typically a "better" brand, or more reputable company will have better quality assurance measures in place, so that you are getting just what you're ordering. A less-reputable brand might sell a spring as a 500lb unit, but it is actually 432lb or whatever.

What you say?

If you want a guarantee of known quality, you'll have to go with a known spring like Eibach, Hypercoil, etc. If you guys have any customers who have used them they could probably give you better feedback than we can. A quick browse through their site shows they have a limited selection, and definitely aren't roadrace-oriented, but that doesn't mean they won't work.

Edit: They are also pretty dang cheap for the size/weight. I'm not sure what to think of that.
